The following describes the possible relay output settings:

NONE This setting disables the relay output.

 RUN The relay energizes when the drive is given a START command, and remains

energized until: a STOP command is given and the output frequency has

deceleratedto0.5Hz,thedrivehas“tripped”,ortheinputvoltageisremoved.

Note that this relay indicates only that the drive is in the RUN mode. It does not

necessarily indicate that the motor is turning.

 FAULT The relay energizes when input voltage is applied to the drive and remains

 /FAULT INVERSE FAULT - The relay energizes when the drive trips into a fault

condition,andremainsenergizeduntilthefaultconditioniscleared.

LOCK FAULT LOCKOUT - This relay is used when the drive is programmed to

automaticallyrestartafterafault.Therelayenergizeswheninputvoltageisapplied

frequency.Toavoida“chattering”relay(constantlyenergizingandde-energizing),

due to small fluctuations in speed. the relay will change states only when the
